Is the system of equations consistent and independent, consistent and dependent, or inconsistent? y=4x−4
y=−4x+4

The given system is

If we sum these equations, we would have

Then, we use this value to find the other

So, the system has a unique solution of .
Now, when a system has at least one solution, it's called consistent. When it has only one solution, it's called independent.
Therefore, the given system is consistent and dependent.
